Kalo pun anda masih bingung, kira-kira kita akan membuat apa ?. Silahkan klik link Live Preview dibawah ini yang merupakan target dari output kita.




Step-1:
Buatlah file index.html seperti code dibawah ini :


<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="utf-8">
	<meta name="viewport" content="width=device-width, initial-scale=1.0">
	<meta name="description" content="tutorial-boostrap-merubaha-warna">
	<meta name="author" content="ilmu-detil.blogspot.com">
	<title>Tutorial Boostrap </title>
	<link rel="stylesheet" href="assets/css/bootstrap.min.css">
	<link rel="stylesheet" href="assets/css/style.css">
	<link rel="stylesheet" href="assets/css/font-awesome.min.css"> 
	<link rel="stylesheet" href="assets/css/bootstrap-theme.css" media="screen"> 
	
	<style type="text/css">
	.navbar-inverse {
		background-color: #3b5998;
		font-size:18px;
	}
	.navbar-brand{
    float: none !important;
}
	</style>
</head>
<body>
	
<div class="navbar navbar-inverse">
	<div class="container">
		<div class="navbar-header">
			<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
				<span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span>
			</button>
			
		</div>
		<div class="navbar-collapse collapse">
			<div id='navigasi'>
	<div class="container">
	<div class='row ab-navigation'>
		<div class='containers'>
			<div class='abnavbar navbar-ab'>
				<div class='navbar-inner'>
					<div class='nav-collapse'>
						<ul class='nav visible-desktop' id='menu-menu-1'>
							<li><a href='/'>Home</a></li>
							<li><a href='#'>World</a></li>
							<li><a href='templates'>Politics</a></li>
							<li><a href='about.html'>Sports</a></li>
							<li ><a href="">Technology</a></li>
							<li><a href='blog'>Music</a></li>
							<li class='kanan'><a href='go/login'>Login</a></li>
						</ul>
					</div>
				</div>
			<div class='nav-line' style='left: 311.234375px; width: 100px; overflow: hidden;'></div>
			</div>
		</div>
	</div>
	</div>
</div>
		</div>
	</div>
</div>
	<!-- /.navbar -->
<script src='assets/js/jquery.min.js' type='text/javascript'></script>
<script src="assets/js/bootstrap.min.js"></script>
<script src="assets/js/ab-navigasi.js"></script>    
</body>
</html>


Step-2:
Membuat file css seperti script dibawah ini :


.abnavbar .nav>li {
float: left;
}
.abnavbar .nav>li>a {
float: none;
padding: 10px 15px 10px;
color: #777777;
text-decoration: none;
text-shadow: 0 1px 0 #ffffff;
}
.abnavbar .nav>li>a:focus,.abnavbar .nav>li>a:hover {
background-color: transparent;
color: #333333;
text-decoration: none;
}

.abnavbar .nav>.active>a,.abnavbar .nav>.active>a:hover,.abnavbar .nav>.active>a:focus {
color: #555555;
text-decoration: none;
background-color: #e5e5e5;
-webkit-box-shadow: inset 0 3px 8px rgba(0, 0, 0, 0.125);
-moz-box-shadow: inset 0 3px 8px rgba(0, 0, 0, 0.125);
box-shadow: inset 0 3px 8px rgba(0, 0, 0, 0.125);
}

#navigasi ul {
list-style: none;
margin: 0;
padding: 0;
}

#navigasi .ab-navigation .container {
position: relative;
}
#navigasi .ab-navigation {
opacity: 1;
background-color: #4e5563;
box-shadow: 0 1px 0 rgba(0,0,0,0.1) inset, 0 -1px 0 rgba(0,0,0,0.1) inset;
min-height: 46px;
-webkit-transition: top 0.3s ease-in-out;
-moz-transition: top 0.3s ease-in-out;
-o-transition: top 0.3s ease-in-out;
-ms-transition: top 0.3s ease-in-out;
transition: top 0.3s ease-in-out;
}
#navigasi .ab-navigation .abnavbar .nav > li > a {
line-height: 25px;
-webkit-transition: all 0.3s ease-in-out;
-moz-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
-ms-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
/*padding: 13px 20px;*/
font-family: raleway,lato,arial,sans-serif;
}
#navigasi .ab-navigation.shrunk .abnavbar .nav > li > a {
line-height: 25px;
-webkit-transition: all 0.3s ease-in-out;
-moz-transition: all 0.3s ease-in-out;
-o-transition: all 0.3s ease-in-out;
-ms-transition: all 0.3s ease-in-out;
transition: all 0.3s ease-in-out;
}
#navigasi .ab-navigation.fixed {
opacity: 0.95;
margin-bottom: 0;
width: 100%;
top: 0;
left: 0;
position: fixed;
}
.navbar-ab .navbar-inner {
background: transparent;
-moz-border-radius: 0;
-webkit-border-radius: 0;
border-radius: 0;
-moz-box-shadow: none;
-webkit-box-shadow: none;
box-shadow: none;
border: none;
filter: none;
}
.abnavbar {
margin-bottom: 0;
float: left;
position: relative;
width:100%;
}

li.kanan {
float: right!important;
}

.nav-line {
background-color: #E31912;
position: absolute;
height: 8%; /* the thick of line on menu*/
bottom: 0;
left: 0;
}

/*Make menu color consistent alhtough hover it*/
.navbar-ab .nav-collapse .nav > li > a, .navbar-ab .nav-collapse .dropdown-menu a {
color: #EFEFEF;
}


Step-3:
Membuat file java script dengan memanfaatkan jquery.


jQuery(function() {
		
		jQuery('.ab-navigation .abnavbar .nav > li > a').animate({ color: '#777777'}, 10);
		jQuery('.ab-navigation').animate({ backgroundColor: '#FFFFFF'}, 100);
		
	    var didresize = false;
	    jQuery(window).resize( function() {

	    });
	    setInterval(function() {
	        if ( didresize ) {
	            didresize = false;
	        }
	    }, 3000);

			jQuery('.abnavbar .nav li').mouseover(function(){
				jQuery( this ).addClass('open');
			});
			jQuery('.abnavbar .nav li').mouseout(function(){
				jQuery( this ).removeClass('open');
			});
				resetNavLine(250);

		jQuery('.nav li').mouseover(function(){
			jQuery('.nav-line').stop();
			jQuery('.nav-line').animate({
				left : jQuery(this).offset().left-jQuery('.ab-navigation .containers .abnavbar').offset().left,
				width: jQuery(this).width()
			}, 250);
		});
		jQuery('.nav li').mouseout(function(){
			resetNavLine(250);
		});
	});

	
	function changeHeader(){
		var y;
		y = jQuery(window).scrollTop();
		
		jQuery('.ab-navigation').stop();
			}
	function resetNavLine(time){
		// didScroll = true;
		jQuery('.nav-line').stop();
		if(jQuery('.nav').children('li').hasClass('current-menu-item')){
			jQuery('.nav-line').animate({
				left : jQuery('.current-menu-item').offset().left-jQuery('.ab-navigation .containers .abnavbar').offset().left,
				width: jQuery('.current-menu-item').width()
			}, time);
		}else if(jQuery('.nav').children('li').hasClass('current-menu-ancestor')){
			jQuery('.nav-line').animate({
					left : jQuery('.current-menu-ancestor').offset().left-jQuery('.ab-navigation .containers .abnavbar').offset().left,
					width: jQuery('.current-menu-ancestor').width()
			}, time);
		}else{
			jQuery('.nav-line').animate({
				width : 0
			});
		}
	}
